Can't comment on that aspect.

Here's what I do to get to the code from a menu but maybe there is a 
quicker way...

Assuming you have set pref: "debugHaloHandle" in "debug" category...

1. Bring up halo on playfield, "menu" halo then "Playfield options"
     (optionally pin this menu for convenience)
2. Shift+rmb over "behave like holder"
     (optionally pin this menu for convenience)
3. On "debug" menu select "explore morph" (so now exploring the menu 
item morph, not the playfield)
4. Note the "selector" is: #toggleBehaveLikeAHolder
5. Click on (highlight) "target": PasteUpMorph
6. Ctrl/Alt-b to bring up a browser for PasteUpMorph
7. #toggleBehaveLikeAHolder is in the "options" category. The one-liner 
should be what you are looking for.

Alternative Etoys-like method, after step 2 open a viewer on the menu 
item itself (or drag out a copy/clone). In the "miscellaneous" category 
is "Menu fire" tile.
